You can tell I'm away on my travels by the number of posts I'm dragging from the entrails of that Tetley specifications manual. I'm not even halfway through the first beer.
When you read this, I'll be judging in Blumenau, Brazil. If I haven't dropped dead. You never know when you get older. Hopefully, they won't have me judging low-alcohol Lager.
Getting to the topic, we're looking at boiling. Starting with the basics. Two coppers, each boiled for 90 minutes. The hops split evenly between the coppers and added at the start of the boil. With pre-boil gravities of 1084º and 1030º.
How does that match up with 1945 practice? Then there were three coppers, all boiled for 120 minutes. No details about how the hops were split, nor when they were added. Pre-boil gravities were 1097º, 1023º and 1004º. So, quite dissimilar.
All the sugar in copper 2, but the caramel in copper 1. Adding the sugar to the weaker wort was standard practice.
